Your network contains an Active Directory domain named contoso.com.
You plan to deploy an Active Directory Federation Services (AD FS) farm that will contain
eight federation servers.
You need to identify which technology or technologies must be deployed on the network
before you install the federation servers.
Which technology or technologies should you identify? (Each correct answer presents part of
the solution. Choose all that apply.)

A.
Network Load Balancing (NLB)

B.
Microsoft Forefront Identity Manager (FIM) 2010

C.
The Windows Internal Database feature

D.
Microsoft SQL Server 2012

E.
The Windows Identity Foundation 3.5 feature

Explanation:
Best practices for deploying a federation server farm
We recommend the following best practices for deploying a federation server in a production
environment:
* (A) Use NLB or some other form of clustering to allocate a single IP address for many
federation server computers.
* (D) If the AD FS configuration database will be stored in a SQL database, avoid editing the
SQL database from multiple federation servers at the same time.
* If you will be deploying multiple federation servers at the same time or you know that you
will be adding more servers to the farm over time, consider creating a server image of an
existing federation server in the farm and then installing from that image when you need to
create additional federation servers quickly.
* Reserve a static IP address for each federation server in the farm and, depending on your
Domain Name System (DNS) configuration, insert an exclusion for each IP address in
Dynamic Host Configuration Protocol (DHCP). Microsoft NLB technology requires that each
server that participates in the NLB cluster be assigned a static IP address.
